SCHOFIELD — A railroad crossing in the city of Schofield is under scrutiny.

The state Office of the Commissioner of Railroads will be investigating the adequacy of the warning devices at the crossing of the Wisconsin Central Ltd. tracks at Northern Road, according to a notice issued this week by the Office of the Commissioner of Railroads.

The crossing is located just south of a switchyard and has been the site of traffic backups, Everest Metro Police Chief Wally Sparks said.

"Some of the businesses have complained that some of the trains have stopped and delayed there for a length of time," Sparks said. The chief said he's not sure whether that's the reason the state is looking into the crossing.

The crossing on Northern Road has signage but no gates, Sparks said.

Calls to the Railroad Commissioner's office and to Canadian National Railway Co., the parent company of Wisconsin Central Ltd., weren't immediately returned.
